Questions & Step-by-Step Solutions

Which algorithm is used for finding the shortest path in a graph?
  • Step 1: Understand what a graph is. A graph consists of nodes (or vertices) connected by edges.
  • Step 2: Know that a weighted graph has edges with values (weights) that represent costs or distances.
  • Step 3: Learn about Dijkstra's Algorithm, which is a method to find the shortest path from one node to another in a weighted graph.
  • Step 4: Dijkstra's Algorithm works by exploring all possible paths from the starting node and keeping track of the shortest distance to each node.
  • Step 5: The algorithm updates the shortest path as it finds shorter routes until it reaches the destination node.
